Hey all,

I've had no luck mounting my SATA-raid 1+0 NTFS drives in Knoppix (or a number of other livecds for that matter). Always get the following error message:

mount: wrong fs type, bad option, bad superblock on /dev/*, or too many mounted file systems

where * is the partition name (sda1 etc).

The (4) partitions are recognised as NTFS in fdisk -l and the above is mount /dev/* /mnt/test -t ntfs -r

One problem appears to be that two different partitions are detected for each real partition, sda1 and sdc1 etc. I suspect this has to do with the 1 (mirror) component of the RAID. If I'm not mistaken you need a patched kernel for proper mirror support. To be honest, I don't care since I only want to read the partitions and in read only mode.

(Other livecds e.g. Gentoo have similar altho they may have different names for the devices e.g. Gentoo has a long scsi name)

As said I have a Promise SATA raid card. Best as I can make out, the 2.6 kernel in Knoppix is supposed to support this and I've tried both.

I've come across http://rcswww.urz.tu-dresden.de/~holzhey/plugscript/doc/knoppix_ataraid_howto.html and http://tienstra4.flatnet.tudelft.nl/~gerte/gen2dmraid/

The first one seems to be mainly about getting raid working to allow you to install Knoppix on a RAID drive which is not what I want and is also for the 2.4 kernel which I believe doesn't support the Promise RAID by default. The second one I've tried without luck.

Anyone hints?

P.S. Unrelated but haven't tried FreeBSD or NetBSD yet. My FreeBSD liveCD (from freebsie) doesn't work, just resets on startup, NetBSD had other probs

I can't help you as I don't have experience with sata raid. Maybe this http://www.linuxmafia.com/faq/Hardware/sata.html and http://www.kerneltraffic.org/kernel-traffic/kt20040918_274.html#17 and http://linux.yyz.us/sata/sata-status.html will help.
